Title: Computer network system
Inventor: ISHIHARA SATORU
IPC: G06F15/16
Filed: 1983-05-27
Abstract: PURPOSE:To make switching easy and to make continuation of a data processing possible by changing an address set to a network interface to process data in another host computer if an optional computer is faulty. CONSTITUTION:If a trouble occurs in a host computer 31 or a magnetic disc 61A or 61B, information indicating that information exchange is impossible because of the trouble of the host computer 31 side is displayed on a terminal 51. When an address code of a network interface 22 is inputted from a keyboard of the terminal 51, the address code inputted from the terminal 51 is set to a storage area of a network interface 41. Thus, the terminal 51 is switched and connected to a host computer 32 through network interfaces 41 and 22, and data from the terminal 51 is processed in the host computer 32 hereafter.

Title: Semiconductor device
Inventor: ADACHI TAKAO
IPC: H01L21/822
Filed: 1990-04-10
Abstract: PURPOSE:To make it possible to lessen a transfer lag due to a long-distance wiring and to improve the operating speed of a semiconductor device by a method wherein signal wirings, which are electrically driven in the same phase, are arranged in parallel to each other. CONSTITUTION:A drive circuit 104 and another drive circuit 105 make a signal of the same phase output. Moreover, a signal wiring 102 for transferring an output signal of the circuit 104 to a passive circuit 106 and other signal wiring 103 for transferring an output signal of the circuit 105 to other passive circuit 107 are arranged in parallel to each other holding a fixed interval. As the circuits 104 and 105 output the signal of the same phase, the time constants of these circuits 104 and 105 are greatly decreased. That is, a transfer lag is decreased. In particular, when the micronization of a wiring progresses and a Calpha becomes small, the thickness of a wiring layer can not be made small so much. Therefore, a Cbeta relatively becomes large and the reduced effect of the transfer lag is increased.

IPC: H04N13/04
Filed: 1990-04-10
Abstract: PURPOSE:To relieve the occurrence of a feeling of disorder by providing a mechanism detecting a noticed point in a display picture of a user and a mechanism matching a display position in the depth direction due to parallax of both eyes of a detected noticed point with an image forming position in the depth position of a picture display panel by an eyepiece lens. CONSTITUTION:An eye tracker 7 detects a noticed point with respect to a screen depending on the position of a pupil of a user. A processing unit 8 Leduces the depth information of the noticed point in contract with a three- dimensional picture data with respect to the detected noticed point. Since the depth is used to calculate the separation width of left and right pictures for parallax of both eyes and the position at which image is formed by the eyepiece lens, a signal generating circuit 9 generates picture signals for left and right eyes separately and an eyepiece drive signal. The position of an imaginary image 4 is made equal to the position of the noticed point in the picture displayed on a picture display panel 3 by using the eyepiece whose focus is variable based on the noticed point of the user as a reference to relieve the occurrence of a feeling of disorder.

IPC: F23D11/02
Filed: 1978-08-02
Abstract: PURPOSE: To enhance the safety of a burning device for liquid fuel by eliminating accumulation of fuel at evaporator when the evaporator is improperly preheated for gasifying the liquid fuel.  
     CONSTITUTION: After an electric heater 2 is energized to preheat an evaporator 1, a motor 20 is driven to thereby rotate a rotary plate 22 fixed onto the rotary shaft 21, a fan impeller 23, and a pump impeller 24. Thus, fuel from a subtank 27 is continuously quantitatively supplied via a pump impeller 24 to the rotary plate 22. The fuel is sprayed and scattered all around of the plate 22 by the centrifugal force. After the atomized fuel is introduced through an opening 13 of a damper 12 to make contact with the inner wall of the evaporator 1, it is mixed with the air from the fan impeller 23 and fed to a burner head 6 to be thus ignited and burned. In this case, if unburned fuel is produced due to certain reason in the evaporator 1, it is returned from a container 10 through a pipe 30 into a tank 27.

CONSTITUTION:The ring-shaped magnet 1 is cut at two places into inequal pieces and the outer  magnetic material 1 is formed by opposing heteropolar each other through the gap 2. A ring- shaped magnet 3, which can be inserted to the outer magnetic material 1, is divided into five  equal parts, heteropolars are opposed through the gap 4 and the inner magnetic material 3 is  formed in such manner that the divided pieces of magnets are sandwitched from both sides by an  inner magnet supporting plate 5, at the center part of which a hole wherein a main shaft 6 will be  passed through is provided. The inner magnetic material 3 is formed in such manner that it is movable along the main shaft 6 using a clutch 7. When the inner magnetic material 3 is inserted  in the outer magnetic material 1, a positional deviation is always generated at the N pole and the  S pole of the inner and outer magnetic materials and turning force is generated by the aid of  attracting force and repulsive force. Through these procedures, a stabilized and high powered  rotary mechanism requiring no power can be obtained.

Title: Crucible for producing single crystal
Inventor: SAHIRA TATEAKI
IPC: C30B27/02
Filed: 1986-04-24
Abstract: PURPOSE:To enable repeated use of a crucible, by placing a detachable cylindrical upper member of a crucible on a bottom-closed lower member of a crucible, detaching and cleaning the upper member of crucible after use and combining the cleaned upper member with a new lower member of crucible. CONSTITUTION:A required amount of granular silicon raw material 10 is charged in a crucible 4 and heated with a heater 5. The silicon raw material 10 begins to melt from the bottom part to form molten silicon 9 and the liquid level reaches a level somewhat lower than the top edge of a lower member 4a of the crucible. A single crystal rod 9A is pulled up from the molten silicon keeping the above state. The lower member 4a of the crucible is deteriorated by the thermal fatigue generated in the lower member 4a, since the inner surface of the lower member 4a of crucible reacts with molten silicon 9 and is exposed to high temperature. On the contrary, such a deterioration does not take place in the upper member 4b of crucible because there is no direct contact of the upper member 4b with the molten liquid 9. After completion of the pulling-up of the single crystal, the upper member 4b of crucible is separated from a susceptor 3 after cooling all parts of the susceptor and washed to remove impurities attached to the surface of the upper member 4b.
